IMPROVEMENT iN SEWING-MACHINES.

Specification forming part of Letters Patent No. 31,214, dated January22, 1861.

To all whom it may concern:

Be it known that I, QUARTUS RICE, of Nevada, in the county of Nevada andState of California, have invented a new and useful ImprovementinSewing-Machines; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which- Figurel is a horizontal section of the machine.' Fig. 2 is a transversesection at y y, but showing the adjusting-screw oi'gage. Fig. 3 is aplan.

Similar letters ot reference indicate corresponding parts in the severalfigures.

The subject of my said invention is a Inachine adapted to sew continuoustubular work of indeinite length for hydraulic hose and analogouspurposes; and it consists essentially in the combination, with sewingapparatus of common form, of guide-rollers and an internal gage,operating as hereinafter eX- plained.

The present illustration represents three needles, A, working side byside in a common needle-carrier, B, reciprocated in guides C by means oflever D and-crank E. These parts, as well 's the spools F,feed-moven'ient G H I, and loopers J, may be of common construction andarrangement, and therefore require no specific description.

K Kl are two parts of a gage, having together anapproximately-cylindrical form, and adjusted in distance asunder bymeans of a shaft, L, having a right and left screw at its respectiveends.

M M are feed-rollers, rotated in direction `of the arrows. In practicethe said rollers are placed at a considerable distance from the gage KK', so that the finished hose will pass freely off the. end of thelatter and between the rollers. u

N N are guide-rollers, formed and placed as shown in Figs. 1 and 2, andmounted upon shafts a a, jourualed in bearings O O', the upper of which,O, are clamped adjustably tothe frame by means of a screwbolt and nut 0,so as to permit the adjustment of the upper ends of the shafts in a lineparallel with the axis of the gage K K,so as to set the rollersvertically or at any needful inclination to vary their effect upon thecloth, as will be hereinafter Y explained.

P is an additional feed-roller, rotated in the and in this position passunder the action of the needles, by which they are tightly stitchedtogether with three parallel seams. The completed hose, after passingoff the end of the gage, is drawn between the feed-roller M, therotation of which imparts to it the needful in termittent motion.

It will be observed that the attachment of V the gage K K is wholly attop and at its rear end, so that the strip of cloth may be introducedbeneath it at back, and after passing the leverj of the loopers may meetwith no obstruction to the connection of its edges. By this meanscontinuous tubing of indefinite length may be produced.

To form tubing of smaller or larger diameter, the distance between theparts K and K of the gage is diminished or increased by the rotation ofthe shaft L.

By setting the upper ends of the shafts a of the guide-rollers N forwardor backward the tightness of the compression of the cloth around thegage may be regulated as desired.

The positions of the cloth and the thread are indicated by red lines.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination, wit-h a sewing-machine of any suitable construction,of the gage K K', constructed and operating, substantially as set forth,to produce continuous tubular work.

2. The adjustable guide-rollers N N, operating in combination with thegage K K', substan tially as and for the purpose set forth.

3. The general combination of the feedmovement G H I M, sewing mechanismA B C D, gage K K', and rollers N P, arranged and operatingsubstantially as and forthe purposes set forth.
